Abstract

The loads and the performance of a wind turbine depend on multiple characteristics of the design. Traditional aero-elastic simulation tools include detailed structural and aerodynamic models of the turbines main components: tower, drive train and blades. Crude assumptions regarding smaller components and actuators are often made to limit modeling complexity, and because the influence of these on the global behavior of the turbine is assumed to be small. However, as the turbine design complexity is increased, i.e. with more radical blade design, the influence of component characteristics might become significant. In this study in the influence of pitch gear characteristics on turbine loads and performance is investigated.
